Vex Robotics Competition 2019 we created a Reverse Ending Stacker which allowed us to pick up blocks in a conveyor belt-like fashion and stacked them. However, we encountered a problem with the extending ramp that stacked the blocks. The ramp’s effectiveness was inhibited because it could not rotate across a wide range. So we decided to create a part that would fix this issue by creating a 360 hinge. The hinge would rotate in 360 degrees.
The robot had a hinge joint that connected to the ramp that pushed the ramp and the stack of blocks on a 45 to 90-degree angle and gravity pushed the blocks down. However, sometimes it would get stuck and it would have been nice to make the ramp go one further angle. This problem would have been solved with the 360 hinges that would have allowed for more ramp movement and better placement for the blocks.
We used Fusion 360 2020 edition to create the 360 hinge with the following tools provided extrude, line, snip, circle, and square. The step by step process is that we started with the base of one of the halves of the hinge, making sure our dimensions were accurate to our sketches. After we finished the base and ensured the dimensions were proportional, we started working on the specific parts that were going to be extruded higher than the rest. Once we had that done and extruded we used the hole tool to add a hole to the center of the hinge which will be where the two halves come together when they’re printed out. Once we had one half done we started on the other half which was pretty much just an inverted version of the other half but instead of a hole in the center of it, it had an extruding cylinder with two tabs on either side to lock the two sides together. After finishing the 3d modeling we were able to test print, once it was done printing we needed to adjust some things to make the halves be able to fit together and after a couple of test prints and adjustments, we had it done and completed.
What we learned from this project is how to use Autodesk 360 2020 edition, how to use Autodesk, and the ability to create 3D models. We would most likely use this project in the future to create 3D models for a job or personal projects. This would be helpful in Robotics because it could allow for an advantage with 3D printed parts that allows the robot to be more efficient. We believe that learning 3D modeling with Autodesk would help with architecture or robotics.
